Application filed July To alt whom it may concern:

Be it known that 1,301? W. PORTMANN, a citizen of the United States ofAmerica, and a resident of Norwood, in the county of Hamilton and Stateof Ohio, have invented a new and useful Improvement in a Separator forStorage Batteries, of which the following is a specification.

An object of my invention is to provide a storage battery separatorwhich will preclude short circuiting of the plates thru formations whichdevelop on the plates.

Another object of my invention is to pro vide a separator for thepurpose stated which is simple in construction and which can be readilyand expeditiously manufactured.

These and other objects are attained by means described herein anddisclosed in the accompanying drawings, in which:

Fig. 1 is a perspective view, part in section, of a separator embodyingmy invention.

Fig. 2 is a fragmental, horizontal, sectional view of a pair of batteryplates having disposed between them a separator embodying my invention,taken on line 22 of Fig. 1.

Fig. 3 is a sectional View on line 3-3 of Fig. 1.

Fig. 4 is a view similar to Fig. 3 showin a modified application ofseparators 'embo ying my invention.

Fig. 5 1s a view similar to Fig. 3 showing another method in theapplication of battery plates embodying my invention.

The separator 6 comprises end posts 7 and 8 which are preferably formedintegral with the intermediate portion .9 of the separator.

The separator may be made of any material commonly employed. inmanufacturing separators for this purpose. '1 he intermediate or bodyportion 9 of the separator has formed in it transverse inclined slots10. The walls of the inclined slots are preferably parallel, and theangle of inclination is such that a perpendicular line cannot be.

drawn from one face of the separator to the other face of the separatorWithout passing thru or touching some part of the separator. In otherwords the upper edge 11, of each of the ribs 12, is disposed above thelower edge ing some portion of 1922. Serial No. 572,894.

13 of the next adjacent rib 12. The posts 7 and 8 may be employed tospace the battery plates 14 and 15.

In Fig. 4 is shown a structure wherein the posts 7 and 8 have theirflush with the side face 18 of the body portion 9 of the separator. Twoseparators are then disposed in such relation to one another that theflush face of the post 7 will engage the flush face of the post 8, andvice versa, whereupon the ribs of the two separators will assume therelation shown by the ribs 12 of the separators A and B shown in Fig. i.

In Fig. 5, one of the separators as is used in Fig. &, isused singlywith the battery plates 14 and 15.

It should be observed that the posts, the ribs, and the body portion ofthe separator are formed integral, wherefore a minimum of labor. andeffort is required to produce said separators. Separators made asdieside faces 16 and 17 closed herein, are sutiiciently rigid and suifiV ciently flexible to give the most efficient service, thefiexibilitypermitting the separator to give rather than to break, andthe rigidity thereof serving to retain the parts in their ori inal andproper relations.

what I claim is:

1. A separator of the class described comprising a. frame carryingintegral spaced ribs forming unobstructed inclined passages thcrethru,the ribs having inclined walls, the

inclination'thereor' being such that no perpendicular line can be drawnbetween the side faces of the separator without contact the separator.

2. A separator of the class described comprising a frame carryingintegral spaced ribs forming unobstructed inclined passagestl1erethru,the walls of the passages beingin, clined to such extent thatthe edges of the ribs on one side of the separator will overlap theedges formed on the next adjacent ribs and disposed on the opposite faceof the sapuratork -In testimony whereof, I have hereunto subscribed myname this 29th day of June,

- ROY W. PORTMANN.
